Objective To analyze the clinical features of immunoglobulin A(IgA) nephropathy(IgAN) occurring in the context of pre-vious acute glomerulonephritis.Methods The clinicopathologic features of 108 cases(77 males,31 females,aged 3.2 to 14.0 years old) of IgAN were analyzed restrospectively with the onset of acute glomerulonephritis in this department from Jan.1994 to Dec.2005.Results Of 108 cases with IgAN,10 cases were with the onset of acute glomerulonephritis. All the 10 cases presented with edema, hematuria and proteinuria.Eight cases had macroscopic hematuria, lasting for 2 days to 2 months.Four cases had recurrent macroscopic hematuria,microscopic hematuria lasting for 16 months.Urine protein qualitative +-+++ lasted for 1-8 months.Two cases had hypertension;2 cases had increasing blood uria nitrogen and serum creatinine.The increase of anti-streptolysin O(ASO) titer was detected in 5 of 9 cases.Two cases had a high titer of DNase-B antibody, and 4 cases had hypocomplementemia.Eight cases had prodromal infection with an interval time varying from 1 to 5 days.Renal biopsies revealed mesangial proliferative glomerulonephritis in 9 cases and focal segmental glomerulosclerosis in 1 case, all with mesan-gial IgA deposition.Conclusions The interval time between the prodromal infection and nephritis symptoms is mostly short in IgAN with the onset of acute glomerulonephritis, while macroscopic and microscopic hematuria remain a fairly long time or recurrently aggravate. Renal biopsy is necessary to diagnose IgAN for this kind of children.

To investigate effects of cultured astrocytes from Sprague Dawley rat cerebral cortex on the development of PC12 cellsderived from rat pheochromocytoma, PC12 cells were cocultured with astrocyte according to different astrocytes/neurons ratio(50:1～1:1) , or with serum-free conditioned medium of astrocytes(ACM). The vitality of PC12 cells was measured by sensi-tive MTT method and their morphologic features were observed by Olympus light microscope. The results showed: (1) WhenPC12 cells were cultured with ACM, compared with the control group, the vitality of PC12 cells was increased significantly (0.255+0. 012 vs 0. 510±0. 036, P<0. 001) and the morphological changes were not obvious in the experimental group. (2) WhenPC12 cells were cocultured with astrocyte in the ratio of 30: 1～1: 1, not only was the vitality of PC12 cells enhanced, but alsothe neurite-outgrowth of PC12 was observed. (3) When PC12 cells were cocuhured with astrocyte in proportion of 50: 10～40 : 1, the vitality of PC12 cells was also enhanced, but the neurite-outgrowth of PC12 was not found. This study suggested en-hancement of PC12 cell-vitality was mediated by soluble factors produced by astrocytes, while activity of the neurite-promotingwas associated with cell-cell contact and with the ratio of two cells.

Objective To study the effect of combining recombinet interferon α -2b gel and loop electrosurgical excision procedure (LEEP) to treat cervical intraepithehal neoplasia (CIN). Methods Prospective, randomly and control study was progressed in 80 patients with CIN Ⅱ-Ⅲ. Before carrying out LEEP, all women were performed high-risk HPV DNA detection by the method of HC2. Among them, forty women were. assigned to be the study group, in which the patients were added to use recombinet interferon α -2b gel for three courses of treatment before and after LEEP, the other forty women who carried out LEEP simply were assigned to be the control group. All patients were examined by hquid-based thinprep cytology test (TCT) and colposcopic site-specific biopsies to doubtful focus of infection in the 3rd, 6th, 9th and 12th month after treatment, and judged the effect by using HC2 in the 6th and 12th month after treatment. Results Eighty patients were not detected residue and recidivafion of CIN diagnosed by coiposcopic site-specific biopsies to doubtful focus of infection. In the study group, 3 women were abnormal detected by TCT, 37 women were negative detected by HC2, the negative rate was 92.5% when LEEP ended 6 months. The cure rate was 100.0% when LEEP ended 12 months. In the control group, 21 women were abnormal detected by TCT, 19 women were negative detected by HC2, the negative rate was 47.5% when LEEP ended 6 months, 8 women were negative detected by TCT, 25 women were negative detected by HC2, the cure rate was 62.5% when LEEP ended 12 months.In the 6th and 12th month after LEEP, the difference was distinguished in the cure rate between two groups. Conclusions There is double interrupted effects by combining recombinets interferon α -2b gel and LEEP to treat CIN. It can raise the one-time cure rate of the patients with CIN.

Objective To investigate the influence on the ovarian reserved function of Gn-RH injection in the bilateral laparoscopic cys-tectomy. Methods The clinical data of 100 patients with endometriosis undergoing bilateral laparoscopic cystectomy were included in this study. 50 patients treated by routine bilateral laparoscopic cystectomy were set as control group. 50 patients treated by Gn-RH injection addi-tionally during the surgery were set as study group. The operative situation,serum FSH level,FSH/LH,E2 level,ovarian reserved function, pregnancy situation and recurrent rate were compared between two groups. Results The operative duration and electrocautery times in study group was significantly less than those in control group(P<0. 01). The residual ovarian tissue capsule wall thickness in study group was sig-nificantly more than that in control group(P<0. 01). At different time points,the serum FSH level,FSH/LH and E2 level in study group were significantly less than those in control group(P<0. 01,P<0. 05). The incidence of ovarian reserved function damage in study group was significantly less than those in control group(P<0. 05). The pregnancy rate was significantly higher and the time between surgery and pregnancy was significantly shorter in study group than those in control group(P<0. 05,P<0. 01). The recurrent rate in study group was sig-nificantly less than those in control group(P<0. 01). Conclusion There is a influence on ovarian reserved function of bilateral laparoscopic cystectomy. By inject Gn-RH during surgery,the ovarian reserved function could be protected,which increase the pregnancy rate and reduce recurrence.

Objective To study the expression of a novel inhibitor of apptosis and survivin in cervical carcinoma and its relationship to the expression of Bcl-2.Methods Using SP immunohistochemical technique, we examined the expression of survivin and Bcl-2 in 59 cervical invasive squamous cell carcinomas.Results Survivin was expressed in 41 of 59 cases(69.5%) of cervical carcinomas. In contrast, no expression of survivin in normal cervical tissues was observed. Overexpression of survivin was related to the tumor grade and clinical stage. Survivin positive cases were strongly associated with Bcl-2 expression(80% versus 35.7%;P＜0.005).Conclusion Apoptosis inhibition by survivin abnormal expression, alone or in cooperation with Bcl-2, may participate in the onset and progression of cervical carcinoma. Survivin is a new diagnostic/therapeutic target in cervical cancer.

Evaluation of the permeability mainly focuses on intestinal absorption in biopharmaceutics classification system (BCS). It is more complicated that the absorption and metabolism under multicomponent environment in biopharmaceutics classification system of Chinese materia medica (CMMBCS) compared with single component environment, which needs suitable mathematical models to be described. Therefore, with full consideration of existing single component mathematical algorithm combining with the characteristics of intestinal absorption and metabolism, we explored and designed a new mathematical algorithm of intestinal absorption and metabolism of multicomponent drug. Then we put forward a new coefficient, P (influence), the relative change rate of the single component's intestinal absorption and metabolism under multicomponent environment compared with single component environment, which described the influences of intestinal absorption and metabolism of the component under multicomponent environment. Moreover, P (influence) highlights the distinctive characteristics of multicomponent drug's intestinal absorption and metabolism, and lays the foundation for the construction of CMMBCS.

AIM: To study the influence of MG132 on the proliferation and cell cycle distribution of NK/T cell lymphoma cells, and to investigate the potential role of proteasome inhibitor on the treatment of NK/T cell lymphoma. METHODS: NK/T cell lymphoma cells HANK1 were treated with proteasome inhibitor MG132, and the proliferation was evaluated by MTT assay. The morphological changes were observed under inverse microscope. The cell cycle distribution and apoptosis were detected using flow cytometry. RESULTS: The growth inhibitory rate of HANK1 cells was(57.72±7.44)% after cultured for 24 h with 1 μmol/L MG132 and was just(3.98±0.07)% after cultured for 24 h with 0.1 μmol/L MG132. The positive relationship between the concentration of MG132 and growth inhibitory rate was observed. On the other hand, after cultured for 24 h with 1μmol/L MG132, the cells in G_1 and G_2 phases were(72.33±3.44)% and(12.86±1.29)%, respectively, much higher than those in control group(63.63%±2.29% and 7.94%±1.91%, respectively). The early and late apoptosis rates in MG132 group were 33.57%±2.10% and 16.66%±0.47%, respectively, much higher than that in control group (7.18%±0.82% and 3.81%±1.06%, respectively). CONCLUSION: MG132 inhibits cell proliferation and induces cell cycle arrested at G_1 and G_2 phases, and cell apoptosis in NK/T cell lymphoma cells in a concentration dependent manner. Proteasome inhibitor may be a good drug to treat patients with advanced NK/T cell lymphomas.
